Training Resource
The Data Center can help you develop your analysis skills. GeneSifter provides an accessible set of microarray analysis tools to explore these datasets. Tutorials assist in reproducing published results, serve as a guide in looking for noteworthy results and prepare you to examine the data on your own.

Research Resource
These datasets can be combined with a user's own data to perform a meta-analysis, providing greater statistical power and insight. With new statistical methods and updated annotation, previously overlooked patterns can be discovered. Bringing new biological questions and knowledge to the analysis of a dataset can lead new discoveries.

CANCER
Gene expression changes provide tremendous insight into the genetic alterations underlying cancer development and progression. Elucidating genes and pathways will not only define the underlying biology of cancer, but also assist in the subclassification of tumors, provide new targets for early diagnosis and suggest treatments.

NEUROSCIENCE
Application of microarray studies in neuroscience provides new ways to examine neurological functions. From studying the differences in gene expression changes between the large and small neurons in the dorsal root ganglia, to identifying the molecular underpinnings of phototransduction to identifying gene expression affected by multiple sclerosis, microarray experiments provide a novel technique to explore the field of neuroscience.
